SS3H10HE3_A/I Equivalent & Substitute Parts

Part Overview

The SS3H10HE3_A/I is a Schottky rectifier diode manufactured by Vishay General Semiconductor - Diodes Division, rated for 100 V DC reverse voltage and 3 A average rectified current in a DO-214AB (SMC) surface mount package. This component is classified as obsolete, necessitating identification of active equivalent parts for ongoing production and design requirements. Substitute parts must maintain identical electrical performance and mechanical compatibility while offering active product status and continued availability.

Substitute Part Grouping Explanation

Substitution of the SS3H10HE3_A/I is determined by strict equivalence across the following electrical and mechanical parameters:

Critical Substitution Criteria:

Voltage - DC Reverse (Vr) (Max): 100 V
Current - Average Rectified (Io): 3 A
Voltage - Forward (Vf) (Max) @ If: 800 mV @ 3 A
Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
Package / Case: DO-214AB, SMC
Mounting Type: Surface Mount
Operating Temperature - Junction: -65°C to 175°C
RoHS Status: ROHS3 Compliant

All identified substitute parts maintain these parameters without deviation. Packaging variants (Cut Tape & Digi-Reel, Tape & Reel) represent distribution formats only and do not affect electrical or mechanical compatibility. The primary distinction between substitutes is product status (active versus obsolete) and current inventory availability.

Engineering Selection Recommendations

Vishay Substitutes (Preferred): The Vishay parts SS3H10-E3/57T, SS3H10-E3/9AT, SS3H10-M3/57T, SS3H10-M3/9AT, SS3H10HE3_B/H, and SS3H10HE3_B/I are direct electrical equivalents to the obsolete SS3H10HE3_A/I. All maintain identical reverse voltage, rectified current, forward voltage, and reverse leakage specifications. These parts carry active product status and ROHS3 compliance. Selection among these variants depends on packaging format requirements: Cut Tape & Digi-Reel formats (SS3H10-E3/57T, SS3H10-E3/9AT, SS3H10HE3_B/I) support lower-volume procurement, while Tape & Reel formats (SS3H10-M3/57T, SS3H10-M3/9AT, SS3H10HE3_B/H) accommodate high-volume production environments.

Cross-Manufacturer Substitute: The MB310_R1_00001 from Panjit International Inc. provides electrical equivalence with one exception: reverse leakage current is specified at 50 µA @ 100 V, compared to 20 µA for Vishay parts. This represents a 2.5× increase in leakage current. The part maintains all other critical parameters and carries active product status with ROHS3 compliance. Selection of this part is appropriate when Vishay alternatives are unavailable and the higher leakage specification is acceptable for the application.

Automotive Grade Consideration: The original SS3H10HE3_A/I carries automotive grade designation with AEC-Q101 qualification. Among active substitutes, SS3H10HE3_B/H and SS3H10HE3_B/I retain automotive grade and AEC-Q101 qualification. Non-automotive variants (SS3H10-E3/57T, SS3H10-E3/9AT, SS3H10-M3/57T, SS3H10-M3/9AT) and the Panjit part lack automotive designation. For applications requiring automotive compliance, selection must be restricted to SS3H10HE3_B/H or SS3H10HE3_B/I.

Frequently Asked Questions (FAQ)

Q: Can SS3H10-E3/57T replace SS3H10HE3_A/I in automotive applications?

A: SS3H10-E3/57T is not automotive grade and lacks AEC-Q101 qualification. For automotive applications, use SS3H10HE3_B/H or SS3H10HE3_B/I, which retain automotive grade and AEC-Q101 certification.

Q: What is the difference between Cut Tape & Digi-Reel and Tape & Reel packaging?

A: Both are distribution formats for surface mount components in DO-214AB packages. Cut Tape & Digi-Reel supports lower-volume orders with flexible quantities. Tape & Reel is optimized for high-volume automated assembly. Electrical and mechanical specifications are identical; selection depends on procurement volume and assembly equipment compatibility.

Q: Is the MB310_R1_00001 a suitable replacement for all applications?

A: The MB310_R1_00001 maintains electrical equivalence for voltage, current, and forward voltage specifications. However, reverse leakage current is 50 µA @ 100 V compared to 20 µA for Vishay parts. Applications sensitive to leakage current or requiring automotive qualification should use Vishay alternatives.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitutes, including the Panjit MB310_R1_00001, carry ROHS3 compliance and REACH Unaffected status.

Q: What is the operating temperature range for these diodes?

A: All parts, including the obsolete SS3H10HE3_A/I and all active substitutes, operate across a junction temperature range of -65°C to 175°C.

Q: Can I use SS3H10-M3/9AT in place of SS3H10-E3/9AT?

A: Yes. Both parts are electrically identical with matching voltage, current, and thermal specifications. The difference is packaging format: SS3H10-M3/9AT is supplied in Tape & Reel format, while SS3H10-E3/9AT is supplied in Cut Tape & Digi-Reel format. Selection depends on procurement and assembly requirements.

Q: Does the DO-214AB package differ between manufacturers?

A: No. The DO-214AB (SMC) package is a standardized surface mount package. Both Vishay and Panjit parts use identical package dimensions and pin configurations, ensuring mechanical and electrical compatibility on PCBs designed for this package type.
